Experientialism \Ex*pe`ri*en"tial*ism\, n. (Philos.)
   The doctrine that experience, either that ourselves or of
   others, is the test or criterion of general knowledge; --
   opposed to intuitionists.

         Experientialism is in short, a philosophical or logical
         theory, not a philosophical one.         --G. C.
